WINDOW-OLE ANING DE VICE Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed April 23,1907. Serial H0 369,810.

1'0 all whom it may concern:

Be it known that I, FRANCIS J. JACKSON, 1L citizen of the United States of America, residing :11 Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful improvements in Window-Cleaning Devices, of which tin.- following is a specification, reference being bud therein to the 110 companying drawing.

This invention relates to window cleaning devices, and the invention has for its object to provide :1 novel device for removing moisture, snow and rain from car windows, the device being particularly designed for street cars whereby a. motorman can clean lire outside of a. platform window and prevent his view frmuiwing obstructed.

To this end, I have devised a. window elcnning' d crimwherein a scraper is movably mounted upon the outer side of the window frame and adapted to engage the pane oi the frame, the scraper being manually moved upwardly and automatically returned to its nornni position. k

The detail construction entoring'into my invention will be hereinafter more fully described and then specifically pointed out in the appended claims.

Referring to the drawing forming part of thisspeci fication, like numerals of reference designate corresponding parts throughout the several views, inv which:

Figure 1 is a front elevation of a window frame equipped with my improved device which is illustrated partly in front elevation and partly in section, Fig, 2 is a vertical sectional view of a window frame illustrating the device in elevation, and Fig. 3 is a detail perspective view of a portion of the scraper and an end connection thereof.

In the accompanying drawing, 1 h-rwe illustrated a Window frame or each comprising side rails l, a. top rsiil 2 and a. bottom rail 3, said rails holding in position a pane of glass 4. Upon the front of the side rails l, I secure two vertically disposed tubes 5, said tubes being provided adjacent each end with flanges 6, whereby said tubes can be secured to the frame or sash by screws 7 or similar fastening moans. The confronting sides of the tubes 5 are slottotL'us at 8, and mounted between said tubes and extending into sold slots is a scraper 1) having a resilient strip 10, such as rubber engaging the pane of glues 4. The ends oi the scraper 9 protrude through the slots 8 into the tubes 5 and are provided with books ii, to engage in openings 12 formed in the upper ends of the shelves 14 right in the tubes 5. The sleeves l4 are suitably connected at their lower end. to elastic cords or cables 15, which pass over grooved pulleys l6, journnlcd in the lower ends of the tubes 5. The opposite ends of the elastic cords or cables 15 are suitably fastened in the upper ends oi the tubes 5, as at 17.

The scraper 9 intermediate its vnds is provided with a. pierced lug l8 and connected to said log is or cable or cold 19 which extends upwardly upon the outside of the window pane 4 and passes over a. grooved pulley 20 jouruulod in the housing 2i mounted in the upper mil 2 of the frame or sash l. The end of ilw cubic or cord 19 upon the inside of the window is provided with u ring or suitablvgrip 32. It will be uppnri-ut from lbe illustration oi my invention that l have devised novel means for cleaning the outer side of :1 window without going outside to accomplish the some. it is obvious that the resilient strip 10 can be easily and quickly re newed at any desired time, and llmt the device mm be made ol' sui-li u size as to cleanse display windows and windows in (la rigorous positions, such as the uppvruze :i

stories of sky-scrapers or b iildings.

The device is priferal constructed of light and durable motel and firi '1 d to correspond to or haw monize with the finish of the @311 or frame upon nhicii it is mounted.

What I claim and desire to secure by Letters Patent,

is: v

1. In a window cleaning device, slotted tunes carried by the side rails of a window frame or sash, grooved pulleys journaicd in the lower ends of said tubes, a scraper ar' ranged between said tubes and having its ends protruding therein, hooks carried by the lnclosed ends of said scraper, sleeves carried by said hooks, elastic cables secured at the upper ends of said tubes and passing downwardly within flutluhos am] over said grooved pulleys and connected to the soul Hli-M'OH. a. resilient strip carried by said scraper, u grooved pulley iourmllcd in the top of said frame or Bush. :1 cable connected to suid scraper and passing upwardly ever sold grooved pulley to the lhncr side of said frame or s ash, and u ring or grip cm-riul by the end of said cable.

2, in a window clcunlng device, slotted tubes carried by lhe side rails of u frame or sash, pulleys journ'uled in the lower ends oi said tubes, :1 scraper arranged between said tubes. hooks ('flllied by the ends of snid scraper within said lulu-s, elzlslic cnhlcs fastened in the upper ends of said lnhos Ind missing downwardly over said grooved pulleys and connecting with said hooks, n grooved pulley Jourunlod in the in]! of sold sash or frame, and 2: cable fustened Io sold scraper and passing upwardly over said grooved policy to the inner side of said frame or sash.

in testimony whereof I nlllx my slguniure in the presence of two witnesses.

FRANCIS. J. JACKSON.
